What the Course Entails and Exam Details

The learning process focuses on mastering the safe operation of double and triple configurations. Core topics covered in the endorsement curriculum and knowledge test include:

• The special air brake systems and connections used for combination vehicles.

• Correct coupling and uncoupling procedures for multiple trailers.

• Crucial pre-trip and post-trip inspections specific to these setups.

• General knowledge on maintaining stability, preventing jackknifing, and handling the extended length and weight.

What to Expect in the Final Exam

To earn the Louisiana Double/Triple Trailers endorsement, applicants must pass a computer-based, multiple-choice knowledge test administered by the Louisiana Office of Motor Vehicles (OMV). This specific test generally contains approximately 20 questions based directly on the material in the Louisiana CDL Manual's doubles and triples section. A minimum passing score of 80% (typically answering 16 out of 20 questions correctly) is required to receive the endorsement. Note that this is a knowledge-only test; no additional practical skills test is needed once you have a base CDL.

How to Study and Exam Centers

The foundational resource for studying is the Louisiana CDL Manual, paying close attention to sections on Combination Vehicles, Air Brakes, and Doubles and Triples. We recommend repeated study combined with taking multiple online practice tests specifically designed for the Louisiana T endorsement, which mimic the actual OMV test structure and content. The actual knowledge test must be taken at a local Louisiana Office of Motor Vehicles (OMV) location during their normal business hours. No third-party centers are involved in this state-administered test.
